回答1:

看了钓鱼人提出的问题,我参考了一下G7变频器说明书。首先安川G7变频器可以安装PG(编码器)选择卡,这种卡是A类,还可以安装速度指令卡、通信卡、监视卡等,各类都有专用插座。A卡的在变频器内左上角,横向。PG速度控制卡有四个型号,A2、B2、D2、X2,A2\B2的输出脉冲最高值是32767HZ,适合最高频率输出下的电机输出频率接近20KHZ的PG,D2\X2的输出脉冲检出最高300KHZ,接线方法为:A2\B2的TA1(2接0V,3+,4-,5+,6- PG电源12V\0V)TA3屏蔽信号。
D2\X2的TA1(2接0V,,4+,5-,6+,7- PG电源12V\0V)TA3屏蔽信号。
你的型号要搞清楚,对应去做就对了。

PG卡是什么?这个我不知道,编码器安装就不一样了,首先你要看多大的电机,然后无非是找好同心度之类的活,大电机可能还需要法兰,有可能还有超速保护,电气方面给你个方向吧,既然是变频器,肯定有主控制板,你去找他的说明说,一般编码器的接入是有8个通道的,首先是电源两个通道,链接到编码器上的电源即可,剩下6个通道分别是A+A-B+B-和零脉冲的+,零脉冲的负,你按编码器上说明书即可,要是变频器只有AB输入,你可能还需要购买一个差模放大板,就是把编码器四通道改两通道输入的东西,名称不一定对,主要是起光耦隔离的作用,这个你安装完编码器相当于要把以前V/F控制改为速度闭环,因此,控制方式你要改变,参数自己找吧,电机需要重新辨识,基本上就是这个样子……

回答3:

变频器(frequency changer / frequency converter)是一种用来改变交流电频率的电气设备。此外,它还具有改变交流电电压的辅助功能。 过去,变频器一般被包含在电动发电机、旋转转换器等电气设备中

回答4:

pg卡有固定的插槽,直接插入变频器就行了
关于接线,说明书上都有。上面仁兄也介绍了。

回答5:

你买了产品的话,相关说明书也会有。上面肯定有说明,照着安装接线就可以。参数也是有对应的说明。
好像安川有起重行业专用软件可以更好的运行变频器。
你又不是单独买个产品,其他相关资料和技术支持都会有的。
